ROLLER BEARING.

Application filed February 16, 1922. Serial No. 536,999.

T 0 old IO/t0"! it mag concern:

.Be it known that I, FRANK O Norms, a citizen of the United States,residing at Baltimore, in the county of Baltimore and State of Maryland,have invented certain newarid useful Improvements in Roller Bearings;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to anti-friction bearings and more particularlyto roller bearings.

The-main object of the invention is to provide an antifriction rollerbearing for car-axles and shafts which shall possess great strength andbe capable of carrying or supporting heavy loads and sustaining severestrains without liability to injury. .The' intention will first behereinafter morepartieularly described, with reference to theaccompanying drawings, whielrare' to be taken as a part of thisspecification, and then pointed out in the claims at the end of thedescription.

In said drawings, Fig. 1 is a perspective view of one member of aroller-retaining and separating cage forming a part of a roller bearingembodying my invention;

Fi .v 2 is. an end view showing the cage members of the bearing inassembled relation; one member of the retaining plate or cap on the nearend of the bearing being removed;

Fig. 3 is a side elevation of a shaft hanger or standard having myimproved roller bearing mounted thereon;

Fig. 4 1s a plan view of one of the rollers detached;

Fig. 5 is a plan view of a modification of the invention;

Fig. 6 is an-end view of said modification' F ig. 7 is a plan view of an'ioditied form V of roller detached; and

Fig. 8 is a plan view of a plain roller that may be used instead of theforms shown in Figs. 4 and 7.

Referring to said drawings, in which the same reference characters areused to. denote corresponding parts in different views, the letter Adenotes one member and A another member of a cage or housing adapted tohold in separated relation a circular series of rollers surrounding ashaft or longitudinal gaps or spindle B of a car axle or the like,eachof said members A. and A" being substantially semi-cylindrical inform and adapted to be secured together between substantiallysemicylindrical memberssg andsCfof an axle box or housinghavingapertured" lu'gsfor ears 0 and c to receive fastening bolts forsecuring the two members O and C togetlier and clamping the roller cageA, A therebetween. In this instance the member C of said axle box orhousing is formed n the upper end of a shaft hanger or standard D onwhich the roller bearmg 1s mounted. The cage members A and A are eachformed or provided with a spaced series of longitudinal roller receivinggrooves a and a, respectively, which are substantially semi-circular inform but greater than a semi-circle so as to leave a spaced series of Igrooves of reduced width on the inner circumference of the cylind'ricalbody. or cage member through which the periphery of a roller E fitted ineach of said grooves may project toward the'cent-er of the united cagemembers A and A thus providinga circular series of spaced rollingsurfaces adapted to contact with the shaft or spindle B. One or bothsections or members A and A 'of the cylindrical lSpdy or cage is formedor protitled with ';a boss or projection a adapted to engage a recess orrecesses in the axle box or hearing members C and C so as to hold thecylindrical body stationary. The rollers are inserted in the grooves orrecesses a and-0i at one end thereof and a cap plate or plates F. and Fbolted or otherwise secured to the end of the cylindrical body, preventsthe rollers from escaping.

The rollers are preferably formed with, reduced portions@"connectingthre, more or less, larger portions 6 so as to provide'oilspaces between the enlarged portions, wherebythe rollers may bethoroughly lubricated, and such enlarged portions may be of the-samediameter their entire length, but it may be desirab-le in some cases toform such enlarged portions so that they will taper slightly in oppositedirections from an intermediate point, as shown in Fig. 7. so as topermit a slight rocking movement. They may however be continuous or ofthe same diameter from end to end, as shown in Fig. 8.

In Fig. 5 of the drawings I have shown a modification inwhich an axlespindle or described with reference to Figs. 1 to 3 of i the drewingsand a series of rollers E? are inserted in. said recesses and securedtherein byimeansof "an annular plate ior adlSk [H 3 bolted or otherwisesecured on. the outer end v of the spindle. In this instanoegatherollers shown have the outerlsurfa'ces of =the enlarged portionsathereof of larger diameter centrally; and .taperingflin opposite direcetions,so' as to permit a slight rockingfmbve ment or freepiay. Insteadof rollers of the formdescribed iplain rollers may b8! used, suchasshown in Fig. 8 of the" drawings and marked E 1 o Having thus}described my invention; what I olaimras new-and desire toseenre byLetters-Patent of =the United States is:-- 1.
